Application fiiecn rn 13.

T all whom-it may concern: 7

Be it known that I, Gnonon lilhwrnzoonmis, citizen of the United Statcs residing at Chicago, in the county of Cook and State of Illinois have invented certain new and useful Improvements in Sausage-- Linking Machines, of which the following is a specification.

This invention relates to improvements in sausage linking machines, and one of the objects of the invention is to provide an improved machine of this character, having means operating to shape the filled easing into links and also provided with means for twistingthe links with respect to each other to form a twisted connecting portion between adjacent links.

it further object is to provideimproved twisting means forthe links which will operate to twist one of the links in one direction and the next adjacent link in the opposite direction, so that the coni'iecting portions between the links will be alternately twisted in opposite directions.

A further object is to provide an improved machine of this character, which will be simple,.durable, cheap and compact" in construction and effective and efficient in operation. To the attainment of these ends and the accomplishment of other new and useful objects as will appear the invention con sists in the features of novelty in substa r tially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention, and in which I Figure 1 is side elevation oi" a of a machine of this character.

Referring more: particularly to the I ings, the numeral 1O desir V supporting structure, which may be or an desired size 1 and configuration and constructed of any suitable material.

Mounted upon the structure are spaced pulleys 11-12; overwhich an endless fiexing handle 192s. sez iarno'; 631,748;

ible carrying clen'ient 13, suclrasa belt opcrates. One of the runs of the belt, passes over a suitable support 14 and; motion may he imparted to the belt in snltable manner. I

Arranged along the edges of the runs-of any desired or.-

the belt 13 which pass over the support 14; are guides 15 for maintaining the casings,

in position. Disposed adjacent one'end of the belt is a rotatable element 16, the periph-v cry of which is preferably shaped to form concaved portions 17 having intermediate edges l8,'which latter are adapted to engage. the filled casing as it is fed'forward on the belt 13 and beneath the element'l-G, to divide the easing into links. This element 16 is given a rotary motion inany. desired or" suitable manner preferably by means of a belt 19, which passes overasuita'ble pulley connected with the element 16 and preterably over another pulley 20, which is con nected for rotation with the pulley 12..

Disposed beneath the belt 13 are'twisting elements designated generally by the reference numerals 21 and These elements 21 and 22 are preferably in the form of bars or rods arranged'parallel with respect toeach other and are movable through suitable guide blocks 23 24:. The blocks2324 are provided with openings 2526. through which the elements 2-122 respectively pass and these blocks are mounted for movement in suitable ways 27 in such a manner that the blocks may be movedtowa-rdsor away from each other. Any suitable means ni'ay be provided for moving the blocks 23-24, such as a double screw 28, h vingan operatwhenthe handle-is moved in one direction the guide blocks 232+'l will move in one di- 29 connected therewith so'that Each ofthesemeinbers 21 22 isprovided with a yieldable work engaging surtacefifi,

constructed 'of any suitable inate rial and r these surfaces are respectively securedtothe elements I 2l22 'iirany suitable manner but are preferably spaced fronithe respective elements by means-oi spac ng projections 31,

orer which the elements pass. one end 32 of each of the; lBH1GI1l S1S anchored inany suitable manner.

The other end ofeach of the elements passesover a suitable projec clearlyin Figure 2. to form an enlarged space or area into which the sausage link passes as it is delivered tromthe end ot' the belt 13. After the casing has been divided into links by the element 16 and as the links are advanced by the conveyor belt 13. one of the links will pass into the recess 35, between the surfaces 30 supported by the elements 21.-22. after which the elements 2l22 are reciprocated with respcct to each other and in opposite directions to twist the link disposed therebetween and thereby twist the connecting portion between adjacent links. This is accomplished by reason of the fact that the yielding surfaces 30 will en age opposite sides oi the link. .Vhen the elements 21-22 have reached the limit of their reciprocating movementin one direction, the directionol' movement will be reversed at which time the ecess 36 of the other yielding surface will be positioned as shown in Figure at to receive the next adjacent link and as the direction of movement of the elements 2l22 will be reversed with respect to each other, the next link which has been fed from the belt will be twisted in a direction opposite to the direction of twisting of the previous link, so that the connecting portion between the next two adj a cent links will be given a twisting movement in a direction opposite to the direction of twist of the next previous link. In other words, the links will be alternately twisted first in one direction and then in the opposite direction; I

Any suitable means may be provided for reciprocating the elements 2122, such as a crank shaft 37 journaled in suitable bear-v ings upon the supporting structure. This shaft 37 is provided with cranks 38-39 connected respectively by means of links lO-- il with the elements 2l22. The points of connection of the links 4t04.-1 with the respective elements are preferably formed by means of extended laterally projected ends 42%3 ot the links, so as to permit the elements 21.22to be shifted laterally with respect to each other and with respect'to the links 40-4t1 during their reciprocating movement so as to permit these elements to be, separated suflicientry that when the direction of movement is reversed they will not engage the link which has just inits the surtaces 30 to be moved away from the work.

The lateral shitting movement may be accomplished. in any suitable manner but preferably by means of cams 41445. disposed on opposite sides of the member 21 and adja cent opposite ends of the surfaces 30 and similar cams 46-4t7 connected with the ole ment 22. These members 2l '22 respectively pass through the openings 25-26 in the guide blocks 2324l.,one pair oil each guide blocks being arranged adjacent each end of the elements 2122 and in positions that the cams 44 l6 at one end of the elements will co-operate with one pair of guide blocks and the cams 453-417 at the other end ot'the ele ments 21-22 will cooperate with the other pair of guide blocks. so that when the cams engage the respective guide blocks the members will be respectively given lateral move ments with relation to each other. Obviously the respective cams on the members 21.22 are so arranged that whenone ofthe cams is active the other will remain inactive.

The cams 44 and 46 are provided for moving the elements 2122 laterally in one direction while the cams 45 i7 are provided for moving the elements in the opposite direction.

As a means for assisting in holding the elements 2l22 in position so that the lateral strain will not displace the members during the twisting movement any suitable means may be provided. To that end there may be provided a guide or track 4C8, which is adjustably secured by means of bolts 49, passing through suitable slots 50 into the supporting structure. A roller 51 is carried by the element 21 and is adapted to pass first on one side and then on the other side of the track 4-8 during the reciprocation of the member 21. A similar guide or track 52 is secured by means 0t fastening bolts passing through suitable slots at to the supporting structure 10. Aroller 55 is carried by the element 22 and is adapted to passfirst on one side and then on the other side of the track 52. These rollers 51 and .55 and the tracks 4-8-52 are so arranged with respect to each other that when one of the rollers passes behind the respective track the other roller willpass in front of its track, as shown more clearly in Figures 3 and 4. i

By the provision of the adjustable guide blocks-25. the elements 21 -22 may be adjusted laterally withaespe ct to eachother to vary the distance between the yielding sure faces 30 so as to compensate varying diam eters of the links and when the partsare 7 -41 also permit of such lateral adjustment,

The shaft 37 may be rotated in anydesired or suitable manner preferably from a drive shaft 56, which receives itsmotion from any suitable source perferably through the medium of a pulley 57, and the shaft 56 is connected with the crank shaft 37 through the medium of intermediate gearing 585960.

It is thought that the operation of this machine will be clearly understood from the foregoing but briefly stated it is as follows;

Assuming theparts to be in the position shown in Figure 2, and assuming that the casing has been'fed forward upon the belt 13 to be divided by the element 16 into links, and that the links project over the portion of the belt which passes over the pulley 11, so that one ofthe links will be disposed in the recessed portion 36 on the element 21, and that motion is imparted to the crank shaft 87. In the position shown in Figure 2, the element 21 has reached the limit of its forward movement, while the element 22 has reached thelimit of its backward movement. Further motion to the shaft 37 will cause the elements 21-22 tomove in the directions indicated by the arrows in Figure 2. It will therefore be manifest'that inasmuch as a link will be disposed between the yielding surfaces 30 of the elements 21-22, and when motion is imparted to reciprocate them in the directions of the arrows in Figure 2,'the surfaces will engage the link to-twist the latter, the roller passing in frontjo'f the track 52 will restrain the element 22 against lateral movement and the roller 51 passing behind the track 48 will permit of a slight lateral movement of the element 21. As soon as the elements 2122 have reached the limit of their movements in one direction, the cranks 3839 will pass over the center of the shaft 37 and the direction of movement of the elements 21-22 will be reversed. In the meantime, however, the links will have been advanced so that the twisted link will drop out from between the surfaces 30'to permit anotherlink to pass therebetween and to be t 'istcdin the opposite direction.

This operationis continued so that the links will be'twisted first in one direction and then inv the other direction so long as the links are fed between the elements 21.- 22.

' The twistedlin-ks maybe caught in any suitable receptacle and conveyed away to any desired point.
